P ( x ) has the given roots: ( i, 7 + 8 i ).
The complex roots of a polynomial P ( x ) with rational coefficients come in pair as:
a + b i and a - b i;
Additional roots are: - i, 7 - 8 i.
In this question, we can determine Maggie car initial speed (15m/s), final speed(0m/s) and the time her car moves (2.5s). Then to calculate the distance she travels, we need to multiply the average speed with time. The equation would be:
Distance traveled= (initial speed+final speed)/2 x time
Distance traveled= (0m/s + 15m/s)/2 x 2.5 second= 7.5m/s x 2.5s= 18.75m
Answer:
9
Step-by-step explanation:
Because I don't know but I think I'm correct.
Answer:
126°
Step-by-step explanation:
(2x +18)° = (3x)°
2x + 18 = 3x
18 = 3x - 2x
18 = x
therefore, (3x)° = (3*18)°= (54)°
The answer is c. You distribute the X to the F and G. f(x) + g(x), which is x + 2.
